Allow filtering nodes by configuration warning status in the scene dock

[mieldepoche]

Describe the project you are working on

prototype

Describe the problem or limitation you are having in your project

related to #8251 There's no easy way to find nodes that have configuration warnings.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

You can filter nodes by name, type or group in the scene dock. Add a way to filter them by configuration warning status.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

• It has to be a letter:thing syntax, but it's hard to find something good for that kind of thing. Maybe w:yes (as opposed to w:no which would then be expected to filter warned nodes out of the selection though that's useless?)?
• There would need to be a button to quickly add the filter, in the ⋮ > Filters menu of the scene dock.

If this enhancement will not be used often, can it be worked around with a few lines of script?

it's an editor feature that would be used a bit

Is there a reason why this should be core and not an add-on in the asset library?

I don't know if this can be an addon

This feels overly specific. Are there really going to be so many "possibly broken" nodes, even in a large scene tree? Clicking on "unfold all" and scrolling down sounds... reasonable enough for me.

[Zireael07]

OP clearly names "configuration warnings" in the title, so "possibly broken" nodes refers to those that have warnings (yellow triangles) on them

[Mickeon]

I am aware of that.

I'd prefer a solution like https://github.com/godotengine/godot-proposals/issues/5068 as it could work globally, rather than being scoped to a specific scene (although you could choose the auditing tool to be scoped to a scene).
